JavaScript - Appended Inputs Are Empty On Submit
Tearing my hair out here. I've got a table where I'm trying to append additional input and file fields when someone clicks a link. The appending works fine, but when I click submit, none of the appended values are being passed through.
I've tried it two different ways (both being appended to the "moreSwatches" table cell: Code: function addSwatch2()
{
var moreSwatches = document.getElementById('moreSwatches');
imgBox = document.createElement("input");
//imgBox.type = 'file';
//imgBox.name = 'swatch[]';
imgBox.setAttribute("type","file");
imgBox.setAttribute("name","swatch[]");
moreSwatches.appendChild(imgBox);
textBox = document.createElement("input");
textBox.type = 'text';
textBox.name = 'swatchname[]';
moreSwatches.appendChild(textBox);
setBR = document.createElement("br");
moreSwatches.appendChild(setBR);
}
function addSwatch()
{
var moreSwatches = document.getElementById('moreSwatches');
var newDiv = document.createElement("div");
addText = '<input type="file" name="swatch[]" style="width: 300px"> <input name="swatchname[]" size="25"><br>';
newDiv.innerHTML = addText;
moreSwatches.appendChild(newDiv);
}
If I hardcode a second set of inputs below the first, it works fine. Anything that is appended is getting ignored. Anyone got any ideas? Similar TutorialsI am trying to make this page work where new posts that get posted to it append smoothly on refresh instead of sliding up and down like they do now. Right now, you hit reply on your post and the entire thing goes up then unfolds again with the new post there, but the place is lost where you were on the paeg and you have to scroll down and I think that is not that user friendly. I want it to just pop or slide down under the existing posts so that the place on the window isn't lost for the user. The profile page is here. I am talking about the profile threads. It's a little bit like a facebook wall. If you need more info I will try and get it. Thank you in advance! I'm setting up an application that involves blog posts with comments boxes appended to the div that contains the posts. The comments boxes are in iframes and load an html file on the same domain. There are multiple posts/boxes on each page. I need a javascript that will only run the append script when the posts are written and appear on the page. So in non js language, I'm looking for this: if div id post#5 appears on the page, show the iframe that contains the comments box that goes with post number 5. else don't show it. I don't know enough javascript to figure this out so if anyone could point me in the right direction, I'd be grateful. Hi, I have a form that when you click submit gives a warning box asking if to continue code below Now when I type in the text field and press enter it doesn't submit nor does it pop up the warning box, how would I do this Code for submit button Code: <script LANGUAGE="JavaScript">
<!--
function submitMyForm()
{
var agree=confirm("ARE YOU SURE ?");
if (agree)
return true ;
else
return false ;
}
// -->
</script>
Code: <form action="admin-delete.php" method="post" name="cp_delete" id="cp_delete"> <input type="text" name="cp_delete_bg" id="cp_delete_bg"> <input type="submit" name="submit" value="submit" onclick="return submitMyForm()"/> </form> I have created some online software which uses form data to submit to another page. The problem is that I have other submit buttons in the same form which submit to different pages (depending on which button is pressed). The first submit button works fine but all the others only work once. Code: <input class="cssbutton" type='submit' value='Button1' onclick="wbform.action='page1.php'; target='mainFrame'; return true;"> <input class="cssbutton" type='submit' value='Button2' onclick="wbform.action='page2.php'; target='_blank'; return true;"> <input class="cssbutton" type='submit' value='Button3' onclick="wbform.action='page3.php'; target='topFrame'; return true;"> <input class="cssbutton" type='submit' value='Button4' onclick="wbform.action='page4.php'; target='topFrame'; return true;"> <input class="cssbutton" type='submit' value='Button5' onclick="wbform.action='page5.php'; target='_blank'; return true;"> <input class="cssbutton" type='submit' value='Button6' onclick="wbform.action='page6.php'; target='_blank'; return true;"> Any ideas my friends? Hi all Is using the real form submit button a problem in any way? Can it actaully send a form when a person uses 'enter' in a text field. When I use this submit, it triggers my validation which is great. Code: <input type="submit" value="OnSubmit validate" /> However this way doesn't seem to trigger my validation although It may solve the above form send problem (if that realy exists). How do I get it to act the same as real submit so it will trigger validation like onsubmit above? Code: <input type="button" value="Send Feedback" onclick="this.form.submit()" /> LT does any of that make sense? all ideas helpful and appreciated I've got the following 2 fields in my form: <input type="file" name="filename" id="filename" value="filename"> <input type="submit" name="submit" value="Upload Image" /> Now I want to hide both of them as soon as the submit button is pressed. Problem is that I'm a javascript noob and I can't find it with google :S Can someone help me? Hi I am making a PC customization website, And I need help wit hthe inputs where you select the parts for the PC. Anyway, I need help for self updating inputs, Like if a user was to select a socket 775 processor, The form would automatically update the motherboard field from --Select a processor-- to a list of socket 775 motherboards. I am quite new at javascript I have never attempted to do anything like this myself, Although I don't know if this would need some PHP in here as well Anyway thanks in advance, Gergy Im trying to dynamically add more fields into my form. HTML: Code: <table id="add_episodes" class="editor" border="0" cellspacing="0" cellpadding="5">
<tr>
<td><input size="3" type="text" name="number" /></td>
<td><input type="text" name="title" /></td>
<td><input type="button" value="Add another text input" onClick="addInput('add_episodes', 'number');addInput('add_episodes', 'title');"></td>
</tr>
<tr>
<td></td>
<td></td>
<td>
<input name="entry_id" type="hidden" value="<?php echo $id; ?>">
<input class="input submit" type="submit" name="submit" value="Add <?php echo $type; ?>">
</td>
</tr>
</table>
Javascript Code: function addInput(divName, type)
{
var counter = 1;
var limit = 50;
if (counter == limit) {
alert("You have reached the limit of adding " + counter + " inputs");
}
else {
var tr.document.createElement('<tr>');
if(type == 'number')
{
var newdiv = document.createElement(element);
newdiv.innerHTML = '<input size="3" type="text" name="number" />';
document.getElementById(add_input).appendChild(newdiv);
}
if(type == 'title')
{
var newdiv = document.createElement(element);
newdiv.innerHTML = '<input type="text" name="title[]" />';
document.getElementById(divName).appendChild(newdiv);
}
counter++;
document.getElementById(add_input).appendChild(tr);
}
}
This is one of my first times working with javascript, usually i work with PHP. Im trying to add more input elements of Code: <tr> <td><input size="3" type="text" name="number" /></td> <td><input type="text" name="title" /></td> </tr> And don't reply that i should make the names into arrays for me to submit more stuff, I'll change that later. But for simplicity and a straightforward problem. I can't get it add more form elements in the correct place or nothing happens at all. Hi Folks I am trying to write a js that validates a form with two text inputs. The two inputs a 'D_techA' and 'D_techB'. I just want to add up (sum) the two input fields (which must be positive numbers) and make sure that they add up to exactly 100 (not more and not less). If they do not add up to 100, then an alert should pop up that says "The two values must add up to exactly 100." I have tried and tried to write a js that does this validation (looking at numerous validation scripts posted in this forum and elsewhere) and I just cannot seem to make it work. I would very much appreciate any suggestions! Thanks! The html code for my very simple form is: <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>Untitled Document</title> </head> <body> <form id="form1" name="form1" method="post" action=""> <label>Investment in Tech A <input name="D_techA" type="text" id="D_techA" /> </label> <label>Investment in Tech B <input name="D_techB" type="text" id="D_techB" /> </label> <p> <input name="Submit" type="submit"/> </p> </form> </body> </html> Is there a way to call everything from one element's onKeyUp (or onBlur, etc.) in another element's onKeyUp, etc? For example, I have something like this: <input type="text" name="val_1" onBlur="sum(['val_2','val_3'],'val_1');"> I would like to be able to do something like this: <input type="text" name="val_4" onBlur=" document.getElementById('val_1').onBlur; percentage('val_2','val_3','val_4');"> But that doesn't seem to work. Is there a way to do this? Thank you! Figured it out. Thanks
Hello everyone! Hi, I am a complete beginner at Javascript(started a few days ago) and was having trouble with some functions. I'm trying to get the inputs required to change based on an option selected in a drop down menu. I was intending to run different scripts based on whatever is chosen but when I ran a test using an alert function, I realized my code isn't working. I went online and found really confusing stuff like "running a for loop through an array to make a dynamic select feature". Still confused any help would be appreciated. My code thus far: Code: <html>
<head>
<title>Practice</title>
<script language="javascript">
function myScript()
{
var loanType = document.form1.loan.options.text
if (loanType == "Bank A")
{
alert("Working")
}
}
</script>
</head>
<body>
<form name="form1">
<select id="loan" name="loan" onchange="myScript">
<option></option>
<option>Bank A</option>
<Option>Bank B</Option>
</select>
</form>
</body>
</html>

I want to make a script that will insert all text type inputs into an array. From there I want to be able to call them and edit them. Here is what I have so far and it is not working. var phone1 = '702' var inputArray = new Array(); var inputs = document.getElementsByTagName('input'); inputs; if (input.type == 'text') { inputArray.push(inputs.id); } inputArray.reverse(); inputArray[0].value = phone1; I'm having an issue adding focus() to an input that is dynamically created with jquery. I'm still learning, so I've mixed in traditional js with my jquery code because it's easier for me to understand. Anyhow document.getElementById(name).style.backgroundColor="#72A4D2"; successfully changed the background of the input ID, but document.getElementById(name).focus(); does nothing. I know that this is the correct code because if I hard code an input into the form (which you can see I've commented out below, such as document.getElementById('password').focus(); it refocuses successfully on that input. Thus I'm stumped yet again. Anyone know how to deal with this issue? JS: Code:
$(function() {
var i = $('input').size() + 1;
$('a.add').click(function() {
$('<p>Username ' + i + ': <input type="text" id="user' + i + '" name="user' + i + '" onblur="javascript:checkl(this.name, this.value);"></p>').animate({ opacity: "show" }, "slow").appendTo('#inputs');
i++;
});
});
function checkl(name, value){
var errors=new Array();
var x;
var msg = "There were some problems...\n";
if (value==="") {
errors['blank'] = "Field must not be blank";
}
for (x in errors)
{
msg += "\n"+errors[x];
}
if (!(x==undefined)){
alert(msg);
document.getElementById(name).style.backgroundColor="#72A4D2"; //works, changed input background successfully
document.getElementById(name).focus(); // does NOT work, no focus
// document.getElementById('password').focus(); // successfully refocuses on hard coded 'password' input
}else{
document.getElementById(name).style.backgroundColor="";
}
}
HTML: Code: <a href="#" class="add" id="1"><img src="add.png" width="24" height="24" alt="add" title="add input" /></a> <form id="target" name="target" action="post.php" method="post" onsubmit="return validate(this);"> <div id="inputs"> <!-- dynamically created inputs here --> </div> <!-- Password: <input type="password" id="password" name="password" size="10"> --> <input type="submit" value="Send"> </form> Hi, I am a complete beginner at Javascript(started a few days ago) and was having trouble with some functions.

Maybe not the best way, but it does the trick. Reply With Quote 01-08-2015, 11:43 AM #3 Philip M View Profile View Forum Posts Supreme Master coder! Join Date Jun 2002 Location London, England Posts 18,371 Thanks 204 Thanked 2,573 Times in 2,551 Posts You have quite a lot of obsolete code:- 1) It is obsolete to assign a name to a form and permitted only for the sake of backwards compatibility. 2) <script language=javascript> is long deprecated and obsolete. Use <script type = "text/javascript"> instead (in fact also deprecated but still necessary for IE<9). 3) Scripts should normally be placed right in front of the </body> tag. Any script can optionally go in the head if you wrap it inside a load event listener so that it can't run before the page loads. 4) Use the value of a select box option, not the text. 5) It is recommended that you place the opening brace following the function, if, else, for, while, do, switch, and try statements on the same line and not on the following line. Apart from that every Javascript statement should be followed by a semi-colon (;). It is quite possible to disregard this advice, but if you do one day it will rise up and bite you in the undercarriage. Code: <html>

The Warrington players can hang their heads high. - Commentator, BBC Radio 2 I have taken lots of programming classes, but am now taking my first web programming class and I am getting sooooo frustrated. I have done lots of looking on the web, but am still unable to figure out why I can not make this simple assignment work. I just need some help with getting something to happen when the user hits submit. What I really want is for a new page to appear with the message using the user inputs, but I would be very happy with just getting the input to appear in the text area that I put in or even for the alert box to pop up with the input. I can work on validation code after I can get some kind of output to work..... I posted everything (due to it's small size), including my attempts to see what is working. Here is the code I have written: Code: <html>
<head>
<title>Name and Age</title>
<script type="text/javascript">
<!--
function Submit()
{
alert("Does this do anything?");
var name = document.forms['NameAge'].elements[0];
var year = document.forms['NameAge'].elements[1];
var date = new Date();
var curr_yr = date.GetFullYear();
var age = (curr_yr - year)
alert("<h3>Hello, " + name + ", you are " + age + " years old."</h3>");
document.close()
/*if (year > curr_yr)
{
alert("You must enter a valid year!");
}
else
{
document.writeln("<h3>Hello, " + name + ", you are " + age + " years old."</h3>");
document.close()
}*/
document.forms['NameAge'].output.value = "<h3>Hello, " + name + ", you are " + age + " years old."</h3>";
}
-->
</script>
</head>
<body>
<h1>Name and Age</h1>
<form name="NameAge" onsubmit="Submit()">
<p align="left">Please Enter Your Name:
<input id="name" maxlength="32" size="24" />
</p>
<p align="left">Please Enter the Year You Were Born:
<input id="year" maxlength="4" size="24" />

I need to style a checkbox, so I made it into two images behind a form with hidden inputs. On click the form takes input from the other form into the hidden fields and POSTs it. Then I use PHP to grab that POST and put it back into the original form. Here are some snippets of what I am trying to do: First form input: PHP Code: <input type="text" name="email" id="email1" value="<?php if(isset($_POST['email2'])) { echo $_POST['email2']; } ?>" style="height:25px;width:270px;" /> Second form input: PHP Code: <input type="hidden" name="email2" id="email2" /> Second form submit image button: PHP Code: <input type="image" src="img/Boxchecked.jpg" value="submit" onclick="fname2.value = fname1.value; lname2.value = lname1.value; email2.value = email1.value" width="20" height="20" /> The forms work fantastic on everything but IE, which does not save the field values. How do I fix the onclick event to save them in IE? Help is much appreciated. Hi all, I am trying to find out if it's possible to auto populate a text input based on the value of another. e.g. there is an input called name.. the user completes this and enters something like John, then in the same form there is another input called username. Once the person enters John in the name field, the username automatically displays John. I'm not sure how doable this is, I'm not very familar with Javascript, so any advice would be greatly appreciated. Many thanks, Greens85 I want to make a search form where inputs only appear if a certain selection has been made. For example the user selects "Green" then the input "X" appears, and if the user clicks "Black" then input "Y" appears. How can this be done? If so, can someone give me a basic example in code that I can use to copy off?
I have the two functions below, I want to write a function that puts them into a chart, I have the chart sorted etc but just struggling with how to get the actual validated users inputs from these two functions into the chart, I've tried document.write('<td> $' + productIndex + '</td>'); into the chart but that wouldn't work anyway as there could be multiple inputs? Just need a way to get the output really. function getProductChoice(min, max) { var getProductChoice = function(min, max){ do{ var productIndex = parseInt(prompt('Enter your product choice; 0-5', '0')); } while( isNaN(productIndex) || productIndex < min || productIndex > max); }; getProductChoice(0,5); } function getProductQuantity(max) { do{ var productIndexQuantity = parseInt(prompt('How many would you like?', '0')); } while( isNaN(productIndexQuantity) || productIndexQuantity < 0 || productIndexQuantity > max); }; getProductQuantity(MAX_QUANTITY); |
